Ideal Bands in Tight-Binding Models
Lexu Zhao, Yang Ge, Shinsei Ryu +1
A band is called ideal when its Dirichlet functional saturates the topological lower bound. We study ideal bands in finite-band tight-binding models with conventional two-dimension…
Defect conformal field theory from Sachdev-Ye-Kitaev interactions
Yang Ge, Shao-Kai Jian
The coupling between defects and extended critical degrees of freedom gives rise to the intriguing theory known as defect conformal field theory (CFT). In this work, we introduce a…
Emergent Spinon Dispersion and Symmetry Breaking in Two-Channel Kondo Lattices
Yang Ge, Yashar Komijani
Two-channel Kondo lattice serves as a model for a growing family of heavy-fermion compounds. We employ the dynamical large-N technique and go beyond the independent bath approximat…
Universal Landau-Zener regimes in dynamical topological phase transitions
Yang Ge, Marcos Rigol
In finite systems driven unitarily across topological phase transitions, the Chern number and the Bott index have been found to exhibit different behaviors depending on the boundar…
Boundary criticality in two-dimensional correlated topological superconductors
Yang Ge, Huan Jiang, Hong Yao +1
The presence of a boundary enriches the nature of quantum phase transitions. However, the boundary critical phenomena in topological superconductors remain underexplored so far. He…
Dynamic mass generation and topological order in overscreened Kondo lattices
Yang Ge, Yashar Komijani
Multichannel Kondo lattice models are examples of strongly correlated electronic systems that exhibit non-Fermi-liquid behavior due to the presence of a continuous channel symmetry…
Boundary criticality for the Gross-Neveu-Yukawa models
Huan Jiang, Yang Ge, Shao-Kai Jian
We study the boundary criticality for the Gross-Neveu-Yukawa (GNY) models. Employing interacting Dirac fermions on a honeycomb lattice with armchair boundaries, we use determinant…
Dynamical Fragile Topology in Floquet Crystals
Jiabin Yu, Yang Ge, Sankar Das Sarma
Although fragile topology has been intensely studied in static crystals in terms of Wannier obstruction, it is not clear how to generalize the concept to dynamical systems. In this…
Topological phase transitions in finite-size periodically driven translationally invariant systems
Yang Ge, Marcos Rigol
It is known that, in the thermodynamic limit, the Chern number of a translationally invariant system cannot change under unitary time evolutions that are smooth in momentum space.…
Crystalline Solutions of Kohn-Sham Equations in the Fractional Quantum Hall Regime
Yayun Hu, Yang Ge, Jian-Xiao Zhang +1
A Kohn-Sham density functional approach has recently been developed for the fractional quantum Hall effect, which maps the strongly interacting electrons into a system of weakly in…
Boundary criticality in two-dimensional interacting topological insulators
Yang Ge, Hong Yao, Shao-Kai Jian
We study the boundary criticality in 2D interacting topological insulators. Using the determinant quantum Monte Carlo method, we present a nonperturbative study of the boundary qua…
Nematic Wigner crystals in rhombohedral multilayer graphene
Yang Ge, Ashwini Malviya, Ethan Angerhofer +2
Recent experiments have reported evidence for Wigner crystals (WCs) in rhombohedral graphene. Here, we investigate Wigner crystallization in rhombohedral tetralayer graphene using…
Dynamic-RKKY induced time-reversal symmetry breaking and chiral spin liquids
Siqi Shao, Yang Ge, Yashar Komijani
We study the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction in various Kondo lattice systems. We argue that the weak Kondo-coupling expansion contains certain physics which is lo…
XekRung Technical Report
Jiutian Zeng, Junjie Li, Chengwei Dai +13
We present XekRung, a frontier large language model for cybersecurity, designed to provide comprehensive security capabilities. To achieve this, we develop diverse data synthesis p…
Perfect state transfer, graph products and equitable partitions
Yang Ge, Benjamin Greenberg, Oscar Perez +1
We describe new constructions of graphs which exhibit perfect state transfer on continuous-time quantum walks. Our constructions are based on variants of the double cones [BCMS09,A…
Large Language Models for Bioinformatics
Wei Ruan, Yanjun Lyu, Jing Zhang +52
With the rapid advancements in large language model (LLM) technology and the emergence of bioinformatics-specific language models (BioLMs), there is a growing need for a comprehens…
A Mean-Field Study of Quantum Oscillations in Two-Dimensional Kondo Insulators
Kaize Wang, Yang Ge, Yashar Komijani
Magnetic oscillations in strongly correlated insulating systems have garnered interest due to oscillations seemingly originating from the bulk, despite an anticipated gapped spectr…
